ROLLS FOR ROLLING RAILWAY-TIES.

SPECIFICATION forming part of Letters Patent No. 364,642, dated June 114, 1887.

Application filed March 26, 1886. Serial No. 196,637. lNo model.)

To all whom it may concern.-

Be itknown that I, FRANgoIs X. Gnonenr,

of St. Louis, Missouri, have made a new and useful Improvement in Rolls for Rolling Railway-Tics,ofwhich the following is a full, clear, and exact description.

The tie produced in part by the rolls in question isaspecial tie employed in an adjustable railway-bedding described in apending application of ini-nefor Letters Patent. The construction produced consists of two upright sides spaced apart,- and between the bottom and the top ofthe tie united by a web, and at the bottom and at the top of the tie each hav- The sides are preferably not" strictly upright, but from the top,or thereabout,downward curve slightly apart,so as to cause the uprights to assume a bracing position and the tie to be moreelastic. Three sets of rolls are employedfirst, the roughing-rolls, then an intermediate set, and then the finishingrolls. The first set consists of'three horizontal rolls, the lower and upper rolls revolving in one direction and the mid dle roll revolving in the opposite direction. Eight passes are made on these rolls. The second set is also composed of three rolls similarly operated. Sixpasses are made on them. The finishing rolls consist of three sets of four rolls'each. Two of the fourrolls are horizontal and two of them are vertical, and they revolve in the same direction.

In the annexed drawings, making part of this specification, Figure 1 1s a front elevation of the roughing-rolls.

then turned one-quarter turn around, and by means of the third pass shaped into the form C; then, without turning it, into the form Fig. 2 is afront elevation ofthe intermediate rolls; and Figs. 3, 3",

D. The bar is then turned one-quarter turn around, and by means of the fifth pass made to assume the form E; then, without turningit, the form F. It is then turned one-quarter around, and by means ofthe seventh pass shaped,

and without turningitaround is,in the twelfth pass, given the shape -L. 'It is again turned,

and in the thirteenth pass shaped as shown at M. The bar is sent through the remaining passes without turning it around,and assumes, successively, the shapes N O P, and finally the shape Q, consisting of the two uprights O C, Fig. 3, united bythe web 0', and each having at the bottom the outwardly-turned flange a, and at the top the outwardly-turned flange c. In the last three passes the flanges 00 are formed. The bar is fed by means of the vertical rolls, or rather by the middle sections, respectively, ofthe vertical rolls, the remaining sections of the vertical rolls and the horizontal rolls serving as bearingsthat is, in forming the fifteenth pass the four rolls R R It R are employed. The upright rolls R R are each composed of three sections-a middle section and two side sections -the roll R having the sections r r r, and the roll R having the sections 1" r51 of which the sections r r are fast on the roll-shafts r r' respectively, and the sections r r and r r loose thereon, respectively. The horizontal rolls R R are each composed'of two sections, 0* W, and are supported upon the shafts r r",'respectively. The sections r1 act to feedthe bar through the pass and to shape the principal portion of that part of the bar included between its upright parts. The upright rolls are also preferably constructed to form the chambers-r wherein the scale that passes between the middle section and side sections may be collected,

and-thence removed laterally through the per- IOO rolls R R acting to contract the bar upright upon the horizontal rolls RIt, the last-named rolls bear against and wear upon each other, and to provide for this wear, and to enable that part of the construction to be readily re uewed, the washers 2" become of use. They receive the wear, and when worn they can be replaced.

By making the rolls RR'R R, sectional the strain upon the structure is greatly reduced, as the various sections can revolve at various rates,respectively,and according to the shapes of those portions of the bar against which the sections respectively bear.

The rolls S S S S and the rolls '1 T T T are constructed upon the same principle of the rolls R R R It, but are modified in shape to conform to the sixteenth and seventeenth passes, respectively. The mechanism for driving the rolls R, &c., S, &c., T, &c., being of the usual character, is not shown; nor is itthought necessary to exhibit that for operating the other rolls. Chambering out the rolls R It, &c., as at r", also is of use, in that thereby the friction between the different sections of the roll is reduced, for it will be seen that its chamber extends into adjoining section or at least from the interior ofone section to the side of an adjoining section.

1. A set of rolls for rolling rail'way-ties, with passes of the respective shapes shown in the accompanying drawings, and therein numbered from 1 to 17, inclusive, substantially as described.

2. The herein-described intermediate rolls with passes of the respective shapes shown in the accompanying drawings, and therein numbored from 9 to 14, inclusive, as described.

3. The herein-described finishing-rolls with passes of the respective shapes shown in the accompanying drawings, and therein numbered from 15 to 17, inclusive, as described.

4. A roll, R, for rolling iron, made in sections 1 1" 1", and having the annular chambers r", as described.

5. The rollsRRR t, in combination, said rolls R" R being made in sections, and having one or more washers, r, interposed between the sections, as described.
